When I use an ampersand (&) in a Category name with spaces in a certain order I get an error that does not allow me to submit the change. Using EE v.2.9.2.
Error: "The data you submitted did not pass our security check."
This seems to be the "invalid_xss_check" error.
I have tried to change the Category group to "Allow all HTML" and to also encode all HTML but I get the same results.
Here is what works and what doesn't work (screenshot below).
Does Not Work:
- "One&Two" ( <--- This is the one I want )
- "One[space]&[space]Two" - (going insane...)
